What it means
A printer sends an invoice with 30-day terms and receives no payment after the due date, so its accounts team calls the customer with the invoice and payment history ready. The call may uncover an administrative delay or a genuine dispute.
Before dialling, check the contract, invoice, due date, credit notes and bank receipts, because a customer may already have paid or the bill may have been sent to the wrong address. Australian government business guidance says to review payment terms and contact customers by phone or other channels to discuss a date or payment schedule.
The UK Small Business Commissioner advises preparation and a calm conversation. These are good practices, not a single legal script for every jurisdiction.
Introduce the purpose plainly by giving the invoice number, amount and due date, then ask whether the customer has received it and whether anything is holding payment up, and avoid opening with an accusation. Listen for a purchase order, tax invoice or approval problem, and if the customer needs a corrected document, assign someone to fix it promptly.
A disputed invoice needs a different route from a forgotten payment, so record which line or service is disputed and who is reviewing it. Where the amount is agreed, ask for a realistic payment date and method.
A useful commitment includes amount, date and any conditions, and 'we'll try soon' is not a date and should not be entered as a firm cash receipt. If the customer can pay only part, clarify the amount, timing and treatment of the remainder, and confirm any payment plan in writing where appropriate without waiving interest or changing contract terms beyond the caller's authority.
Record the name and role of the person reached, the time, facts discussed and next action, handling contact details according to privacy rules. A clear note prevents another colleague from repeating the same question or overlooking a promise.
Verify payment after the promised date, since a transfer receipt or verbal assurance does not always mean cleared funds are in the company's bank. Keep a consistent follow-up cadence, with room for the relationship and dispute context, because repeated calls at unreasonable times can be counterproductive or unlawful.
Measure outcomes carefully: if 64 of 100 calls are followed by payment within seven days, the observed rate is 64%, which does not prove the calls caused every payment. For owners, a collection call is an evidence-gathering and follow-up step, and the right person should make it, since a finance clerk can check payment status while an account manager may be better placed to resolve a service dispute.
In practice
Real-world examples.
Example
A caller checks an invoice seven days overdue and agrees a specific payment date with the authorised customer contact. The caller notes the date, the amount and the person who agreed to it.
Example
The customer says the invoice lacks a purchase order number, so the supplier fixes the document and records a new follow-up. The call turns a stalled invoice into a payable one.
Example
Finance logs a partial-payment plan and checks each amount against the bank before closing the account. Any missed instalment triggers a prompt follow-up rather than a surprise at month end.
Formula
Calculation
Observed seven-day payment rate = calls followed by cleared payment within seven days / calls in the cohort x 100. 64 / 100 x 100 = 64%; the measure is not proof of causation.
To judge the value of the effort, suppose the 64 invoices averaged $2,500. Cleared cash within seven days is 64 x $2,500 = $160,000. If a comparison group with no calls paid at a 50% rate, the calls may have contributed 14 extra payments, or 14 x $2,500 = $35,000, which is a fairer estimate of their effect than the full $160,000.Case study
Seen in the real world.
This entirely fictional example follows Oasis Print, an invented printer. A customer did not pay an overdue invoice because an old purchase order number was missing. The collections clerk found the issue on a call and asked billing to correct the document. The customer then gave a dated payment plan, which finance checked against actual receipts.
The case does not claim a measured reduction in days sales outstanding. The clerk added a short checklist to the call notes covering purchase order, tax invoice, approver and payment date. Later calls took less time because the same questions were asked in the same order, and disputes were routed to the account manager sooner. Oasis Print is invented for illustration.
Watch out
Common mistakes.
- Calling before checking credits, bank payments and the contractual due date.
- Pressuring a customer while ignoring a specific invoice dispute.
- Treating a vague promise as cleared cash without a record or follow-up.
